"To paint on the DNA-looking design, using a super-thin striper brush and drawing down the center of your nail, make two short archs on the left and two longer ones on the right, creating the illusion that they're crossing each other," she says.

Add the stitching

"Using the same striper brush and the dark gray polish in the above steps, draw a dash at the base of each arch along the side of your nail," says Whitehill. "This gives it that cable knit finish. Next, clean off your striper brush or use the end of a toothpick, pour out a little bit of the deep gray paint, and dip the tip into the lacquer followerd by a tiny bit of nail polish remover to thin out the polish. Then, lightly tap the end of the brush or toothpick a bunch of times in between the main cable knit designs to make it look like the sweater's stitching."
